[Buildroot] [PATCH] systemd: Allow building with no init system

[Trent Piepho]

It's possible to build systemd, and use the systemd libraries, on a
target with no init system.

While installing systemd when trying to use SysV init will result in
systemd clobbering the SysV system and vice versa, it may well work when
no init system has been selected.  For instance, when building an SDK
the sytemd headers and libraries might be necessary but there is no
reason to have an init system selected.  Someone creating a custom init
system might also want some of the systemd libraries.
